Embodiment Construction

[0049] Hereinafter, preferred embodiments of the present invention will be described in detail using the drawings. In addition, the embodiment described below does not limit the content of the present invention described in the scope of the claims. In addition, not all the configurations described below are necessarily essential components of the present invention.

[0050] figure 1 It is a schematic diagram showing the configuration of the sheet manufacturing apparatus according to the embodiment.

[0051] The sheet manufacturing apparatus 100 described in this embodiment is, for example, dry-type used waste paper, such as confidential paper, which is used as a raw material, to fibrillate, pressurize, heat, and cut to manufacture new paper sheets. Optimal installation of paper. It is also possible to improve the bonding strength or whiteness of paper products by mixing various additives into the fibrous raw materials and combine them with uses, or to add functions such as ...

Abstract

The present invention provides a sheet manufacturing apparatus and a method of controlling the sheet manufacturing apparatus for suppressing web or sheet clogging at the start of sheet manufacturing by the sheet manufacturing apparatus. The sheet manufacturing device (100) is provided with: a second web forming unit (70), which processes fibers into a web; a sheet forming unit (80), which passes through the second web forming unit (70) and is processed into The sheet-shaped second material (W2) is clamped and conveyed; the control part controls at least one of the pressurized state and the conveyed state at the sheet forming part (80), and the control part controls according to the second material The top end of the sheet ( W2 ) is affected by the conveying speed of the sheet forming part ( 80 ) and the gripping of the sheet forming part ( 80 ) relative to the position of the gripping part of the sheet forming part ( 80 ) that grips the second web ( W2 ). At least one of the pressure and the nip width of the sheet forming part (80) is controlled so that the second web (W2) passes through the nip part.

Description

technical field [0001] The invention relates to a sheet manufacturing device and a control method for the sheet manufacturing device. Background technique [0002] Conventionally, there has been practiced a method of depositing fibrous substances and applying a bonding force between the deposited fibers to obtain a sheet-like or film-like molded body. As a typical example thereof, a method of producing paper by papermaking (papermaking) using water is mentioned. In many cases, the paper produced by the papermaking method generally has cellulose fibers derived from wood or the like entangled with each other, and partially bonded to each other by a binder (paper strengthening agent (starch paste, water-soluble resin, etc.)). A bonded structure (for example, refer to Patent Document 1). [0003] However, since the papermaking method is a wet method, a large amount of water needs to be used, and dehydration, drying, etc. are required after the paper is formed, and the energy a...
